Частотные преобразователи относятся к сложной промышленной электронике достаточно дорогой и в тоже время широко распространенной по всему миру. На сегодняшний день трудно себе даже представить какое-либо производство, на котором бы не работало данное промышленное оборудование.
К сожалению, в процессе эксплуатации выходит из строя даже самое надежное промышленное оборудование. В данной статье мы разберем частотный преобразователь KEB, точнее коды ошибок частотного преобразователя KEB COMBIVERT F5 серии BASIC, COMPACT и GENERAL, с полной расшифровкой. Частотники в наше время нашли широкое применения в абсолютно всех сферах промышленности управляя как мини моторами в оргтехнике, так и гигантскими двигателями в горнодобывающей промышленности.
Для простоты общения со столь сложной электроникой все частотные преобразователи оснащены небольшими дисплеями с помощью которых выводятся информационные сообщения с кодами ошибок, расшифровав которые можно сразу же узнать причину ее возникновения. Если учесть распространенность данной промышленной электроники, то появляется острая нужда в расшифровке кодов ошибок частотных преобразователей.
Данная статья поможет даст вам возможность не совершать ошибок, и в добавок поможет самостоятельно определять и устранять ту или иную причину повлекшую за собой аварийную остановку частотного преобразователя KEB.
В частотниках KEB COMBIVERT все сообщения, связанные с ошибками, отображаются вместе с буквой “E” после которой указывается сама ошибка на дисплее преобразователя. При сообщении об ошибке частотный преобразователь KEB автоматически отключает модуляцию. Повторный запуск частотника возможен лишь после сброса ошибки.
Сбой в работе преобразователя обозначается буквой “А” соответственно после которой отобразится соответствующие сообщение о сбое оборудования. Сбой в работе частотного преобразователя может быть вызван различными причинами.
Сообщения о состоянии привода выводятся без дополнительных символов, данные сообщения показывают текущее рабочее состояние частотника такое как (непрерывное вращение вперед, удержание в нуле и т.п.).

Parameter Description — Encoder Set Up
70
This parameter displays the type of encoder feedback installed in
the drive. It is also used to confirm a change in the encoder
feedback card when a different card is installed or a change of
motor encoder when an absolute encoder is used.
Normally it is not necessary to make any adjustments to this
parameter and the value display is for informational purposes
only. However if the feedback card in the drive has been changed
or the absolute encoder has been disconnected or changed use
the following steps to clear the resulting error message.
Feedback Card Installation
On installation of a new feedback card the drive will display
E.ENCC. To acknowledge the new encoder card go to this
parameter press function and one of the codes below will be
displayed and press enter. This confirms the installation of the
new card.

IncIE

I24PE
15-24V HTL incremental
EndAt
EnDat
Absolution encoder exchange or re-connection
If an absolute encoder (Hiperface, EnDat, SinCos, SSI) is disconnected
or reconnected it could indicate that the absolute position of the
encoder has changed. Therefore it may be necessary to re-aline the
encoder to the motor. If the drive senses that the encoder has been
disconnected or exchanged it will always trigger the error E.ENCC. To
acknowledge the change and clear the error, select this parameter, it
will show one of the codes listed above, then press enter. The error
should be cleared and normal operation can continue.
If the encoder was physically removed from the motor and
mounted again, it will be necessary to realign the encoder to the
motor. For further assistance see parameter LF.77 and section
5.11.1.

Какая-то засада нарисовалась. Частотник КЕВ F5-Lift. Пульт подключен через удлинитель. Станция ШК6272. При подключении в станции нулевого защитного провода РЕ на частотнике вылетает переходной блок, через который к частотнику подключается выносной пульт.
Пока в станции не был подключен РЕ, все было нормально, частотник запрограммировался. При подключении РЕ, на пульте высветились все восьмерки. Отключил РЕ, подключил пульт напрямую к частотнику – пульт работает.
На сайте КЕВ нашел письмо, в котором пишется о возможно неправильном расключении разъема в кабеле энкодера. Этот кабель пока не проверял. Но там пишут, что вылететь может энкодер или плата сопряжения энкодера с частотником, про этот блок не упоминают. Кто-нибудь сталкивался с подобным? Экспериментировать больше не хочется, два блока уже вылетело.
Еще не могу найти информации по микросхемам в этом блоке:

Кажись, вычислил засаду. Ситуация следующая: в обоих блоках вылетела одна и та же микросхема 7LB179, по восьмой ноге (вход приемника) коротыш на общий питания. По схеме эта нога соединена с выходом передатчика МАХ488 (пятая нога), расположенном в разъеме, втыкаемом в выносной пульт.
Контактная площадка в цепи пятой ноги МАХ488 расположена на самом краю печатной платы и этим краем печатная плата касается крепежной втулки в корпусе разъема. Стоит на разъем слегка нажать и восьмая нога 7LB179 оказывается соединенной с корпусом разъема. Если корпус разъема соединен с защитным РЕ, микросхеме наступает кирдык.
Предполагаю, что с такой конструкцией подобный инцидент будет не последним.

Добрый вечер. Не могу запустить KEB. При адаптации пишет 1 OPE. В описании этого нет.

это вроде не завершенного процесса… Попробуй станцию переключить (выключить -включить).

Скорее сообщение о недопостимости операции. Тут не
(выключить -включить).
тут скорее просто выключить плату и попробовать протестировать с отключеной платой.

Сообщение I_OPE возникает при вводе параметров в защищенные ячейки памяти преобразователя, когда на входе безопасности (клемма 16) присутствует сигнал разрешения работы. Как выше написал Наладчик, говорит о недопустимости операции.

При попытке автотюнинга — идентификации двигателя
(Прописываем параметры мотора и энкодера, LD.14 ставим в 1, нажимаем Enter,
зажимаем контакторы KM2 и KM5) вылетает ошибка E.Hyb (ранее вылетала E.encC).
Не тот энкодер или просто с ним нет связи? Вариант 1 при подключении к станции ШК6272. Лебёдка WSG 1.3.
Кто-нибудь может описать алгоритм автотюнинга поподробнее?
Обязательно-ли делать обучение системной позиции (LC.18 —> 4, LC.19 —> 1)?
Или кто-то запускал вышеописанные комплекты?
Записан

Для начала необходимо проверить кабель энкодера, артикульный номер кабеля укажите. Обучение системной позиции делать обязательно.

В документе BA_WSGS1_E11.pdf указано, что может быть два вида энкодеров на лебёдке WSG-S1.3
1) SSI oder EnDat (ERN 413, энкодер Хейденхан)
2) 1 sine and cosine signal with 1 per/rotation (ERN 487, энкодер тоже от Хейденхан)
К счастью, одинаковых по числу импульсов и вольтажу.
Кто-нибудь сталкивался с этими двумя вариантами?
Артикульный номер пока не скажу — объект в 16 км. от меня.
когда на входе безопасности (клемма 16) присутствует сигнал разрешения работы.
Т.е. надо делать тюнинг при несобранной ЦБ?

SinCos энкодер ERN487 выдает синусоиды, а не меандр. В остальном обычный инкрементальный энкодер.
EnDat (ECN 413 или ECN 1313) выдает точно такие же синусоиды (если не частотник не пользует дополнительные каналы, то может работать с ним как ERN — формат ничем не отличается) плюс данные по цифровому каналу. Это абсолютный энкодер и по цифровому каналу может передавать данные о точном положении вала в любой момент времени.
Отличать или по маркировке или по концам (если кабель не перепутали, но это достаточно тяжело — разъем у энкодера разный и впридачу сам разъем нестандартный — хрен найдешь такой).
Если есть проводники R+, R- значит точно ERN.
Если есть CLOCK и DATA (тоже плюс и минус) значит точно EnDat — не путать с сигналами C+/C- и D+/D- которые есть у ERN — назначение их совсем разное.
Скорее всего стоит все таки EnDat…

Заменили кабель энкодера, автотюнинг запустился и благополучно был завершён.
Движение было в противоположную сторону, путём изменения
LC.13 0 -> 1 -> 17 добился правильного направления.
LC.16 меняется от 16000 до 60000.
Лифт движется из МП, прокинув подвесник, убрав одну из перемычек, добились движения из «ревизии».
Вернули старый кабель энкодера — работает (ранее, видимо, был неконтакт).
Жаль,что на пульте частотника нет индикации текущих значений частоты, напряжений, величины тока.
Монтаж лифта продолжается.

Ребята, подскажите в чём засада? Пытаемся запустить лифт в монтажную ревизию, забили параметры по инструкции быстрого ввода в эксплуатацию КЕВ f5 lift. с синхронным двигателем. Провели идентификацию двигателя. Всё прошло успешно. На станции ШК-6272 тоже всё в норме. При пуске включаются контакторы главного привода а реле к7и контактор тормоза КМ4 не включаются. Станция пишет «нет снятия тормоза». Провода расключены правилно, обрывов нет. С уважением.

Лифт отработал 3 года ШУЛМ двигатель асинхронный.При пуске включается контактор главного привода а реле KV19 не включаются. Пробовали Ld.14 и Ld15. местами менять с соответствующей заменой проводов в разъёме. Может включится, а может и нет. Когда не включается реле тормоза частотник пишет ошибка E. br. Кидал провод с разъёма частотника напрямую к плате с реле KV19-909 и 132 на колодку в другие места. Несколько раз проедет нормально,потом опять вылетит. Фишкой реле принудительно включал, тормоз отрабатывает нормально. Идеи для танцев с бубном закончились. Все провода протянуты и проверенны.

Value Description
The correct evaluation of the system position is no longer ensured. The error E.EncC can
only be reset via parameters Ec.00/LC.11.
Exception ! An error, due to wrong encoder increments (value 70), is immediately reset,
once the correct encoder increments are adjusted. Attention, if the control release is still
set, the modulation is enabled !

Какая-то засада нарисовалась. Частотник КЕВ F5-Lift. Пульт подключен через удлинитель. Станция ШК6272. При подключении в станции нулевого защитного провода РЕ на частотнике вылетает переходной блок, через который к частотнику подключается выносной пульт.
Пока в станции не был подключен РЕ, все было нормально, частотник запрограммировался. При подключении РЕ, на пульте высветились все восьмерки. Отключил РЕ, подключил пульт напрямую к частотнику – пульт работает.
На сайте КЕВ нашел письмо, в котором пишется о возможно неправильном расключении разъема в кабеле энкодера. Этот кабель пока не проверял. Но там пишут, что вылететь может энкодер или плата сопряжения энкодера с частотником, про этот блок не упоминают. Кто-нибудь сталкивался с подобным? Экспериментировать больше не хочется, два блока уже вылетело.
Еще не могу найти информации по микросхемам в этом блоке:

Кажись, вычислил засаду. Ситуация следующая: в обоих блоках вылетела одна и та же микросхема 7LB179, по восьмой ноге (вход приемника) коротыш на общий питания. По схеме эта нога соединена с выходом передатчика МАХ488 (пятая нога), расположенном в разъеме, втыкаемом в выносной пульт.
Контактная площадка в цепи пятой ноги МАХ488 расположена на самом краю печатной платы и этим краем печатная плата касается крепежной втулки в корпусе разъема. Стоит на разъем слегка нажать и восьмая нога 7LB179 оказывается соединенной с корпусом разъема. Если корпус разъема соединен с защитным РЕ, микросхеме наступает кирдык.
Предполагаю, что с такой конструкцией подобный инцидент будет не последним.

При попытке автотюнинга — идентификации двигателя
(Прописываем параметры мотора и энкодера, LD.14 ставим в 1, нажимаем Enter,
зажимаем контакторы KM2 и KM5) вылетает ошибка E.Hyb (ранее вылетала E.encC).
Не тот энкодер или просто с ним нет связи? Вариант 1 при подключении к станции ШК6272. Лебёдка WSG 1.3.
Кто-нибудь может описать алгоритм автотюнинга поподробнее?
Обязательно-ли делать обучение системной позиции (LC.18 —> 4, LC.19 —> 1)?
Или кто-то запускал вышеописанные комплекты?

В документе BA_WSGS1_E11.pdf указано, что может быть два вида энкодеров на лебёдке WSG-S1.3
1) SSI oder EnDat (ERN 413, энкодер Хейденхан)
2) 1 sine and cosine signal with 1 per/rotation (ERN 487, энкодер тоже от Хейденхан)
К счастью, одинаковых по числу импульсов и вольтажу.
Кто-нибудь сталкивался с этими двумя вариантами?
Артикульный номер пока не скажу — объект в 16 км. от меня.
когда на входе безопасности (клемма 16) присутствует сигнал разрешения работы.
Т.е. надо делать тюнинг при несобранной ЦБ?

SinCos энкодер ERN487 выдает синусоиды, а не меандр. В остальном обычный инкрементальный энкодер.
EnDat (ECN 413 или ECN 1313) выдает точно такие же синусоиды (если не частотник не пользует дополнительные каналы, то может работать с ним как ERN — формат ничем не отличается) плюс данные по цифровому каналу. Это абсолютный энкодер и по цифровому каналу может передавать данные о точном положении вала в любой момент времени.
Отличать или по маркировке или по концам (если кабель не перепутали, но это достаточно тяжело — разъем у энкодера разный и впридачу сам разъем нестандартный — хрен найдешь такой).
Если есть проводники R+, R- значит точно ERN.
Если есть CLOCK и DATA (тоже плюс и минус) значит точно EnDat — не путать с сигналами C+/C- и D+/D- которые есть у ERN — назначение их совсем разное.
Скорее всего стоит все таки EnDat…

Заменили кабель энкодера, автотюнинг запустился и благополучно был завершён.
Движение было в противоположную сторону, путём изменения
LC.13 0 -> 1 -> 17 добился правильного направления.
LC.16 меняется от 16000 до 60000.
Лифт движется из МП, прокинув подвесник, убрав одну из перемычек, добились движения из «ревизии».
Вернули старый кабель энкодера — работает (ранее, видимо, был неконтакт).
Жаль,что на пульте частотника нет индикации текущих значений частоты, напряжений, величины тока.
Монтаж лифта продолжается.

Провели идентификацию двигателя. Всё прошло успешно. На станции ШК-6272 тоже всё в норме. При пуске включаются контакторы главного привода а реле к7и контактор тормоза КМ4 не включаются. Станция пишет «нет снятия тормоза». Провода расключены правилно, обрывов нет. С уважением.

Пробовали Ld.14 и Ld15. местами менять с соответствующей заменой проводов в разъёме. Может включится, а может и нет. Когда не включается реле тормоза частотник пишет ошибка E. br. Кидал провод с разъёма частотника напрямую к плате с реле KV19-909 и 132 на колодку в другие места. Несколько раз проедет нормально,потом опять вылетит. Фишкой реле принудительно включал, тормоз отрабатывает нормально. Идеи для танцев с бубном закончились. Все провода протянуты и проверенны.

Initial Start Up 5. Initial Start-up 5.1 Selecting The Confi guration Before trying to operate the drive it is necessary to establish the correct mode of operation. The F5 drive is capable of driving different types of motors both open and closed loop. Therefore prior to operation, the type of motor and mode of operation (open or closed loop) must be established.
-
Page 57: Setting The Control Type
Initial Start Up 5.3 Setting The Control Type The COMBIVERT drive supports six different control modes, digital speed selection and control, analog speed control, analog torque control. The drive’s I/O will need to be set up according to the desired scheme. From the table below select the desired control scheme and adjust the corresponding number in parameter LF.2.

Initial Start Up 5.6 PM Synchronous Motors 5.6.1 Motor Overload The COMBIVERT drive is capable of providing solid state motor overload protection. If it is desired that the drive provide this protection, turn the function “on” in parameter LF.08. The drive uses the motor current from LF.12.
-
Page 61: Auto-Tuning Pm Motors
Initial Start Up 5.6.3 Auto-Tuning PM For best performance the resistance and the inductance of the PM motor motors must be measured by the drive. Use the following steps to complete the measurement for PM synchronous motors. Set up 1) Make sure the rated motor speed (LF.11), rated motor current (LF.12), rated motor frequency (LF.13), rated motor torque (LF.17) and contract speed (LF.20) are entered into the drive before you begin.
-
Page 62: Machine Data
Initial Start Up FAIL : the measurement sequence was interrupted, i.e. the inspection switch was released prematurely, or the controller dropped the enable signal to the drive. Verify if the controller is dropping the signal by fi rst setting LF.3 to conf and try again. If the controller still drops the enable and the motor contactor, the problem lies in the controller.

Page 66
Initial Start Up Initial Steps 1) Verify the motor is correctly connected to the drive, i.e. phase U->U, V->V, W->W. With PM motors you can not have an arbitrary phasing. If direction reversal is required, the system direction can be reversed in LF.28 after the pole position is learned. -
Page 67: Absolute Encoder Setup (No Ropes)
Initial Start Up FAILd: The encoder position samples are not consistent within 4,000 counts after 11 samples. In this case try the procedure again and note the learned values. If all displayed values are consistent, it would be sufficient to use an approximate average and enter it into LF.77.
-
Page 68
Initial Start Up the actual position value of the encoder. As the motor moves this value will change. When the motor rotor has aligned with a pole, the value will stabilize. At this point, the alignment has been found. Continue holding the inspection switch as the drive will then try to move the motor clockwise and counter clockwise to verify the motor’s rotation is consistent with the encoder’s. -
Page 69: Absolute Encoder Setup (With Ropes)
Initial Start Up The following will outline the procedure for aligning an absolute encoder for 5.11.3 Absolute Encoder use with a permanent magnet motor and the following encoders: HIPERFACE, Setup (with ropes) ENDAT, SIN/COS. The motor must be mounted in place and be electrically connected to the elevator controller.
-
Page 70
Initial Start Up Alignment Process 1) Set LF.3 = P Lrn. The display should confi rm with StArt. 2) Press and hold the inspection up switch. Motor current will begin to fl ow in one phase and the current will ramp up to the motor’s rated value. The motor sheave should turn slowly and then stop when the motor rotor has lined up with one of the motor poles. -
Page 71: Absolute Encoder Position Verifi Cation
Initial Start Up 4) For high speed runs under load, it may be necessary to raise 0.LF.36 to a higher value. This value should not be set to a value higher than the motor manufacturer’s peak torque value, usually 2.0 to 2.4 times the motor’s rated torque.
